IMPROVEMENT IN DEVICE FOR SCUTTLING- VESSELS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern:

Be it known that I, J oHN HAIIL, of Marsheld, in the county of Plymouth,and State of Massachusetts, havel invented a new and improved Gate forScuttling Ships; and I do hereby declare the following to be a full,clear, and exact description of the construction and operation of thesaine, reference being had to the accompanying drawings, making a partof this speciiication, in which- Figure l is a vertical section, throughthe line x of iig. 2.

Figure 2 is a side elevation.

The object of this invention is to construct and at tach to vesselsagate, which can readily be opened,. for the piu'pose of scuttling them,and which can aftery ward be as readily closed, when it is desired topump out and raise the vessel.

In the drawings, A represents a portieri 'of the hull of the vessel,having an opening, a, through which the water is to be admitted, inseuttling the vessel, and D is the deck.

A shorttubeor pipe of metal, O, cast or wrought, is made, and insertedinto the opening a, being provided with anges c c', which t tightlyagainst the wall, around the opening a, on both the inside and outsideof the vessel, being provided with a central opening, to admit thewater. The inner flange c is expanded so as to forni ahed, to supportthe gate and its guides and stays, and allow the gate to slide up anddown, so as to cover or uncover the mouth of the opening a.

The bed, thus for1ned,'is provided with raised anges e e along itssides, which have longitudinal guide-grooves along their inner edge,where they jointhe bed-plate a, in which grooves the gate G slides.

Stays 's s may be employed to strengthen the several parts, in themanner shown in the drawings.

`A rod, R, bent to conform to the wall of the vessel,v

extends from the upper edge of the gate G, through a guide,'g, up towardthe deck D, just beneath which it is attached to a vertical screw-rod,by a swivel-j oint, F. rIhe last-mentioned rod, M, extends up throughthe deck, and terminates in a crank or handle, H.

A plate, P, is attached to the deck, provided with a female screw,through which the male-screw rod M eX- tends. I

By turning the handle H in one direction or the other, the rod M isscrewed up or down, carrying with it'the gate G, and opening or closingthe aperture af.

The whole device is simple and cheap, and can be operated at any momentfrom the deck.

-Having thus described my invention,

What lI claimas new, and desire to seclue by Letters Patent, is-

The device above described, consisting essentially of the metallic pieceC, having the flanges c o, the
